Description :
Optical fiber connectors are used to join optical fibers where a connect/disconnect capability is required. Due to the polishing and tuning procedures that may be incorporated into optical connector manufacturing, connectors are generally assembled onto optical fiber in a supplier’s manufacturing facility.
Every fiber connection has two values:
Attenuation or insertion loss
Reflection or return loss.
Measurements of these parameters are now defined in IEC standard 61753-1 .
Features of good connector design:
●Low insertion loss
●High return loss (low amounts of reflection at the interface)
●Ease of installation
●Low cost
●Reliability
●Low environmental sensitivity
●Ease of use
Optical fiber connectors are used in telephone company central offices, at installations on customer premises, and in outside plant applications to connect equipment and cables, or to cross-connect cables.
